Additions for the Kent G3 Hybrid Inverter (10 / 12 / 15 kW three-phase). Run the Common checklist first; this list never applies to Kent M1.
For trained/authorized installers only.

​
Platform pre-checks

  • Altitude — site at or below 4000 m. Pass: confirmed.
  • Mounting angle — vertical within ±5°; clearances per the G3 figures including bottom ≥ 500 mm above ground and fan sides (left in, right out) clear. Pass: measured and photographed. 📷
  • Grounding — external grounding conductor and heat-sink ground terminal connected per the manual figure. Pass: both landed, photographed. 📷
  • Phase rotation — rotation meter at the grid terminals; terminals matched to utility L1-L2-L3. Pass: rotation correct, no phase alarm at boot.

​
Power-up & first configuration (on-device HMI)

  • DC switch discipline — the DC switch is operated only with string current below 0.5 A (clamp-ammeter check). Pass: rule followed at every operation.
  • Power ON in the G3 sequence — grid AC ON first; complete first-time setup; then PV DC switch and battery breaker ON. Power-off is the reverse, battery first. Pass: clean boot.
  • Advanced settings only via the partner-gated password — day-to-day commissioning uses the standard HMI menus; the professional menu is opened only by authorized crews (password partner-gated, never shared). Pass: no unauthorized professional-menu changes.
  • Quick Setting completed in the HMI order — Time → Meter/CT → Grid code → Storage mode → Battery setting. Pass: each step confirmed and photographed. 📷
  • Battery model = the actual Kent battery entry — select the LV battery-brand protocol family (Kent F1 pairs via the Kent comm cable); selecting nothing or the wrong model raises a battery-name failure. Pass: model set, live SOC shown. 📷
  • Grid code set per Kent parameter sheet for the site’s DISCOM. [KNB-VAL-01 — never improvise grid parameters]

​
Three-phase behaviour

  • Per-phase load test — step a known load on each phase; each phase must feed its own load with correct CT mapping. Pass: per-phase readings correct.
Pending Kent validation. [KNB-VAL-06] The shipped-firmware default for per-phase (unbalanced) output and the 150% unbalanced-load figure are under bench confirmation. Until published here: do not promise more than 100% of the per-phase rating on any single phase, and record the per-phase test results.
  • Backup transition — open the grid breaker with real essential loads. Pass: loads ride through; clean return.

​
Alarm handling rule

  • If any alarm shows at boot: power off, wait 5 minutes, restart once; if it persists, stop and escalate — do not cycle repeatedly. Pass: rule followed and code recorded. 📷

​
Common mistakes

  • Operating the DC switch under load “because it clicked fine last time” — the 0.5 A rule is an arc-prevention rule.
  • Skipping the Installer login and configuring from a user session.
  • Carrying Kent M1 habits (menu password, parallel DIP positions) onto this platform.
